WP Prism Syntax Highlighter enables you to use Prism by Lea Verou in your WordPress blog.

Prism is a lightweight, extensible syntax highlighter, built with modern web standards in mind.

  • It has an easy and convenient code editor integrated into the WordPress editor toolbar: you can insert code in just one click.
  • It requires no configuration at all, however you can still customize the default settings in the plugin’s settings page.

It supports all Prism features, namely:

NOTE: the plugin archive contains

  • all languages definitions
  • no plugin
  • default theme

It is recommended to use only what you need in order to keep the plugin the smallest possible.
Please download your custom Prism from and upload the files in:

  • your_plugin_directory/wp-prism-syntax-highlighter/css/
  • your_plugin_directory/wp-prism-syntax-highlighter/js/
    Do NOT replace the original prism.css and prism.js, you will lose all your changes as they get overwritten when updating the plugin!

Why another Prism plugin?
If you searched the plugin directory, you certainly noticed that there are several Prism plugins for WordPress. Well, none of them satisfied me: one plugin had no code editor, the other didn’t escape HTML tags, another didn’t have the options I needed… so I made a new one to suit my needs.


  • Integrated code editor
  • Highlighted C++ code
  • Plugin settings


  1. Download the plugin archive from and unzip it
  2. Upload the wp-prism-syntax-highlighter folder to your plugin directory (usually wp-content/plugins)
  3. Activate the plugin (Plugins > Installed Plugins)
  4. If you get a warning from the plugin asking you to edit your theme, please do it as you might experience visual bugs (requires about 30 seconds of your time)
  5. Highlight some code!


Q: how can I install WP Prism Syntax Highlighter?
A: please see the Installation page.

Q: what is the warning I get when I enable WP Prism Syntax Highlighter?
A: some themes (like the Twenty ones included into WordPress by default) already include some CSS to prettify code blocks. It might interfere with Prism and you might experience visual bugs. That’s why it’s recommended to comment out or remove any CSS code related to pre or code tags.

Q: how do I disable line wrap?
A: by default Prism does NOT wrap lines. It’s certainly your theme’s fault (Twenty themes are known to do that). Search for line like word-wrap: break-word; and comment it out.

Q: what to do if I encouter a bug?
A: please open an issue. However, make sure the bug is related to the plugin itself and not to Prism. If you think it’s a Prism bug, please open an issue here.
